TRB’s National Cooperative Highway Research Program (NCHRP) Report 552: Guidelines for Analysis of Investments in Bicycle Facilities includes methodologies and tools to estimate the cost of various bicycle facilities and for evaluating their potential value and benefits.  The report is designed to help transportation planners integrate bicycle facilities into their overall transportation plans and on a project-by-project basis. The research described in the report has been used to develop a set of web-based guidelines, available on the Internet at http://www.bicyclinginfo.org/bikecost/, that provide a step-by-step worksheet for estimating costs, demands, and benefits associated with specific facilities under consideration.
